The AC Store, on of three stores in Unalakleet

I was invited to a bon-fire up on Army Hill.  The menu includes s’mores.  I went to the store to see what it would cost to purchase the s’more ingredients.  Here are photos of the Graham Crackers, Hershey Bars and Marshmallows from the Alaska Commercial Store in Unalakleet.  Compare the cost of the same ingredients from your local grocery store.  What is the difference in cost?  What about percentage of cost between the two sources?  Why do you suppose the prices are different?
